Organophosphonate Utilization by the Wild-Type Strain of Penicillium notatum [PDF]

Applied and Environmental Microbiology, 1995
We studied the biodegradation of compounds containing phosphorus-to-carbon bonds by using a wild-type strain of Penicillium notatum. The substrate specificity of this strain was studied, and we found that it is able to utilize structurally diverse organophosphonates as sole sources of phosphorus.

Novel amine templated three-dimensional zinc-organophosphonates with variable pore-openings [PDF]

, 2017
Five new amine-templated zinc-organophosphonate compounds have been synthesized hydrothermally in the presence of zinc, 1-hydroxyethane-1,1-diphosphonic acid (H(4)hedp) as the diphosphonate ligand and different aliphatic amines.

Organophosphonate Utilization by the Thermophile Geobacillus caldoxylosilyticus T20 [PDF]

Applied and Environmental Microbiology, 2002
ABSTRACT A strain of Geobacillus caldoxylosilyticus from central heating system water could utilize a number of organophosphonates as the sole phosphorus source for growth at 60°C. During growth on glyphosate, aminomethylphosphonate release to the medium was observed, and in cell extracts, a glyphosate ...

Chiral‐Induced Spin Selectivity Effect in a 1 nm Thin 1,1′‐Binaphthyl‐2,2′‐diyl Hydrogenphosphate Self‐Assembled Monolayer on Nickel Oxide

Advanced Science, EarlyView.
A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.

A fluorescent substrate for carbon-phosphorus lyase: towards the pathway for organophosphonate metabolism in bacteria [PDF]

, 2009
Udgivelsesdato: 15 October 2009Many species of bacteria can use naturally occurring organophosphonates as a source of metabolic phosphate by cleaving the carbon-phosphorus bond with a multi-enzyme pathway collectively called carbon-phosphorus lyase (CP ...

Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

Chemistry – A European Journal, EarlyView.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

Formation of Layered Proton-Conducting Zirconium and Titanium Organophosphonates by Topotactic Reaction: Physicochemical Properties, Proton Dynamics, and Atomic-Resolution Structure [PDF]

, 2019
A series of new zirconium and titanium phosphates-organophosphonates, in which the organophosphonate moiety is functionalized with a sulfo group, was prepared by a topotactic reaction involving the gamma modification of zirconium or titanium hydrogen ...

Organophosphonate utilization by the wild-type strain of Pseudomonas fluorescens [PDF]

Applied and Environmental Microbiology, 1992
The wild-type strain of Pseudomonas fluorescens was found to utilize a range of structurally diverse organophosphonates as its sole carbon or nitrogen sources. Representative compounds included aminoalkylphosphonates, hydroxyalkylphosphonates, oxoalkylphosphonates, and phosphono dipeptides.

A Novel Polyphosphate‐Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii

Environmental Microbiology, Volume 28, Issue 7, July 2026.
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.
